JAMES ANSON COCHRANE, OF CINCINNATI, IOWA.

To all whom it mag concern:

' Be it known that I, JAMEsANsoN OocHRANs, a c itizenof the United States, residing at Cincinnati, in the county of Appanoose and State of Iowa, have invented certain new and useful Improvements in Tooth-Brushes,

. of which the following is a specification.

Direct the principal objects of my invention is to provide a tooth-brush with a concave-convex disk fitted to the handle to form a liquid-tight connection between l said disk and handle] to prevent saliva and dentiirices fromsoiling the hand of the userand being disagreeable and unsanitary; and another object is to utilizethe concavo-convex disk as a stopper for a casing adapted to contain the bristle end of the brush.

To accomplish these objects and to secure other and further advantages in the matters of construction, operation and use, my improvements involve certain new and. useful arrangement orcombination of parts and details of construction, which will hereinafter be described and then pointed out in the claims at the close of this specification.

In the drawings forming part of this specification,- Figure l is a plan view of a tooth brush made in accord.- ance with my present invention. Fig. 2 is a longitudinal sectional view of a slight modification of the saine. Figl .3 is a plan view and partial section of a tooth brush embodying my improvements, showing the casing. in'

which the topth brush is adapted to be placed.

Referring'to the drawings for a more particular description of this invention, the numeral 1 designates a tooth brush which may be of any desirablje character and contour,'having a handle 2, which may be of any I Specification of Letters Patent. I

tion. In the form of my invention shown in Figs. 1 and 3, the handle and headportions ofthe stock are formed of a single piece of material.

In 'the form of my invention shown in Fig. 2, the handle portion 2' oi the stock is detachable from the head portion. Said handle portion has a projection 3 at its inner end, forming a shoulder on said end, and said projection has its outer portion tapered and screwthreaded as at 5. The head portion has a similarlyshaped, screw-threaded socket to receive said projection. The shield in both forms of my invention serves asa stopper for the month end of the casing 6, shown in Fig. 2.

Various changes in the form, proportion and minor details of construction may be resorted to without dcparting from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent, is:-

1. A tooth brush provided with a groovesurrounding the handle of the same at a point between the brush head and the portion gripped by the hand in using the brush. and a concavo-convex elastic disk having a central aperture therein; said aperture being normally smaller than the handle at the base of the groove, and said disk being fitted in said groove to form a liquid-tight connection be tween said disk-'and shank to prevent saliva and dentifrices from soiling the hand of the user.

2. in combination with a casing open at one end. :1 tooth brush having an elastic disk connected to the handle thereof, and forming a stopper for the open end of the cusing. for the purpose set forth.

3. A tooth brush provided with an elastic shield secured to the handle portion thereof, and a casing for said tooth brush, the opening in which is slightly smaller than the shield, substantially as described.
